Description

Projectile Firing Apparatus This invention relates to projectile firing apparatus and particularly to apparatus which is detachably mountable on a guA, especially apparatus for firing grenades.
Attempts have previously been made to provide grenade launchers which are attachable to rifles. However, such arrangements nave not been satisfactory in a number of respects. For example in order for the launcher barrel not to extend ton far beyond the rifle barrel, the trigger has had to be operated from an unconventional position which has often led to the handle being unusable and the magazine thus forming the handle of the gun. Furthermore in this situation the gun is improperly balanced for accurate firing.
According to the present invention there is provided projectile firing apparatus comprising barrel means, means for detachably mounting the apparatus on a gun with the barrel means lying substantially parallel to the barrel of the gun, trigger means and means permitting a projectile to be loaded into the barrel means.
Preferably the apparatus is so constructed that when the apparatus is mounted on a gun the trigger means is located adjacent the trigger of the gun, and the handle of the gun is desirably freely usable. The trigger means of the apparatus may be immediately below the trigger of the gun.
Preferably also the means for mounting the apparatus on a gun includes two brackets mountable on the barrel of the gun at locations spaced from one another. The trigger means may be provided on a mounting fixedly mountable on the brackets and the trigger means may include a pivot arrangement whereby the barrel means may be pivotally mounted on one of the brackets and pivotable relative to the m uniting. The barrel means may include a locking attachment for co-operation with the mounting.
The trigger means preferably includes a firing bolt which is movable in a direction substantially perpendicular to the direction of firing.
Means may be provided for locking the barrel means in a required orientation relative to the trigger means to permit firing.
An embodiment of the present invention will now be described by way of example only with reference to the accompanying drawings, in which Fig. 1 is a side view of part of an apparatus according to the invention; Fig. 2 is a sectional side view of the apparatus of Fig. 1; Fig. 3 is a view from one end of the apparatus of Fig. 1; Fig. 4 is a view from the other end of the apparatus of Fig. 1; nd Fig. 5 is a diagrammatic side view showing the apparatus of Fig. 1 mounted on a gun.
The drawings show apparatus for firing 40mum calibre grenades, the apparatus being mountable on a standard infantry small arms rifle, for example a British SA80.
The apparatus comprises a mounting 10 contoured to fit beneath such a rifle. A pair of spaced lugs 12 are provided adjacent a front end 14, of the mounting 10 with aligned holes 16 provided through the lugs 12. A bolt 18 with a 'T' shaped head 19 is rotatably mounted through the mounting 10 at a location rearwardly spaced from the lugs 12, with the head 19 on the same side of the mounting 10 as the lugs 12.
The rear end 20 of the mounting 10 has a lug 22 extending from the side of the mounting 10 opposite to the lugs 12. A trigger assembly 24 is mounted on the outer side of the lug 22. A catch 26 is provided on the other side of the lug 22. The catch 26 is spring urged towards the front end 14 but may be manually moved against the spring by a knob 28 connected to the catch 26 and located adjacent the free end of the lug 22.
The apparatus also includes a first bracket assembly 30 mountable on the gun's barrel. The assembly 30 comprises a first portion 32 of inverted U-shaped section with a semi-circular indent in the upper face of the base 34.
The side limbs 36 are so spaced to provide a sliding fit between the lugs 12. Aligned holes are provided through the limbs 36. A second portion 38 also has a semi-circular indent ir- one side thereof which is engageable with the indent Lii the first portion 32 to clamp the barrel of the gun therebetween. A plurality of self-tapping screws 40 are provided through the second portion 38 to hold the first and second portions 32,38 together. A pin 42 is locatable through the aligned holes 16 to mount one end of the mounting 10 to the bracket 30.
A second bracket assembly 44 is also mountable on the gun's barrel. The assembly 44 includes a sleeve 46 slidable on the barrel and locatable thereon by two selftapping screws 48. A plate 50 is mounted on the side of the bracket 44 facing the mounting 10, by self-tapping screws 52. A slot 54 is provided through the plate 50 into an opening 56 therein. The mounting 10 may be mounted on the bracket 44 by the head 19 of the bolt 18 passing through the slot 54 into the opening 56 and the bolt 18 being rotated so that the head 19 enages in the opening 56 across the slot 54.
The apparatus further includes a barrel 58 threadably mounted in a carrier 60 which is located intermediate of the length of the barrel 58. The carrier 60 includes a lug 62 extending perpendicularly from the barrel 58 with a through hole 64. The lug 62 is of a size to slidingly fit between the side limbs 36, with the hole 64 aligned with the holes in the limbs 36 and the lugs 12 to permit the pin 42 to pass thelXthrough and pivotally attach the barrel 58 to the gun. The breech end of the barrel 58 engages wit the catch 26 to hold the barrel 58 against the mounting 10 ready for firing.
The trigger assembly 24 is secured to the mounting 10 by a plurality of screws 66. The assembly 24 includes a hollow contoured firing bolt 68 slidably movable in a direction parallel to the length direction of the lug 22 and spring urged towards the gun. For clarity the bolt 68 has been shown by hatched lines in Fig. 2.
lFle upper end of the bolt 68 has a step 70 facing away from the barrel 58. The step 70 is engageable, when the apparatus is cocked, with one end of a trigger pin 72.
The pin 72 is slidably movable in a direction parallel to the barrel 58 and is urged by a spring 74 towards the barrel 58. The pin 72 is connected adjacent its other end to a conventional pivoted trigger 76.
Located above the bolt 68 is a firing pin 78. The pin 78 is slidably movable in a passage leading from above the bolt 68 to an opening 80 in the lug 22 and thereby into the barrel 58, and is spring biassed away from the opening 80. The end of the pin 78 nearest the bolt 68 has angled faces which meet along a line perpendicular to the direction of movement of the bolt 68 and the pin 78. The pin 78 narrows towards its other end by way of two shoulders to an end portion of a size to slidably fit through the opening 80.
A pivoted cocking lever 82 is provided on a one side of the assembly 24 and is engageable with the bolt 68 whereby pressing of the lever 82 pushes the top of the bolt 68 below the trigger pin 72 to engage therewith. A safety catch mechanism is provided comprising a cylindrical pin 84 with a notch along the length thereof. The pin 84 rotatably extends through the other side of the assembly 24 and a handle 86 is provided on its free end. The pin 84 engages in a recess 88 provided on the upper side of the trigger pin 72 (unless the notch is aligned therewith) to prevent movement thereof.
A further safety feature is provided in that when the catch 26 is pushed in towards the assembly 24 to release the barrel 58, a pin 90 on the side of the catch 26 facing the assembly 24, engages in a one of two holes (not shown) in the bolt 68, one hole for when the apparatus is cocked and for when it is not, to lock the bolt 68 in position.
In use, the bracket assemblies 30,44 are mounted on the barrel of a gun in the required positions, the assembly 44 within a heat shield for the gun and the assembly 30 forwar' of the shi(?ld. The mounting 10 is fitted onto the assemblies 30,44. The barrel 58 with the carrier 68 thereon is fitted to the mounting 10. The apparatus is now ready for use. Fig. 5 shows the apparatus fitted to a gun 100 showing the trigger 24 located adjacent, i.e. below, a trigger 102 of the gun 100, with a handle 104 of the gun 100 being therchy free for use. The position of the barrel 58 when ready for loading is also shown in dotted lines.
To load the apparatus the breech end of the barrel 58 is released from the mounting 10 by pressing the knob 28, simultaneously disabling the bolt 68 with the pin 90. A grenade is slid into the barrel 58 and the barrel 58 is pushed back past the catch 26.
The apparatus is now cocked by pushing the lever 82 which slides the bolt 68 below the trigger pin 72 the latter sliding across under the force of the spring 74 to engage ith the step 70. If required the safety mechanism may now be applied by turning the handle 86 in an anticlockwise direction so that the pin 84 engages in the recess 88, disabling the trigger pin 72.
To fire a grenade, the safety mechanism must be disengaged if applied by turning the handle 86 in a clockwise direction. he trigger 76 is pulled moving the trigger pin 72 off the step 70. The firing bolt'68 is then spring urged upwards to impact the sloped end of the firing pin 78 which is pushed towards the barrel 58 so that the end portion of the pin 78 passes through the passage 80 to fire the grenade.
There is thus described a grenade launcher mountable on a standard small arms rifle which permits the rifle to be handled in the normal way, as the launcher's trigger is adjacent the gun's trigger and the gun's handle is unobstructed. The launcher is of relatively simple construction and can thus be inexpensively and robustly manufactured. The design of the launcher means that it may be made relatively lightweight. The launcher is readily detachable from the rifle.
Any suitable sight may be fitted on the launcher and this may be attached using a hole 92 in the mounting 10.
Screw means 94 may be provided for fine adjustment of the launcher's alignment.
Conventionally the bracket assemblies 30,44 would be maintained a I ned on the rifle but the rest of the launcher would be readily removed or mounted thereon.
Various rnodifications may be made without cielDartinrJ from the scope of the invention. for example the housing may be attached to the barrel of the gun by different methods. A different trigger mechanism could be used.
Alternative means could be provided for loading the barrel.
